combined with urea to form a, solid substance,-but this product is so unstable as to have no commercial value. I have discovered that by the addition of small quantity of. ncetanilid a relatively stable solid substance may be obtained which when dissolved in Water will form a solution of hydrogen peroxid.

As a specific instance, my process carried out tollo vs: 600 grams of urea are dissolved in 1000 grams of hydrogen peroxid from Z; to 25% in which has been dissolved 2 giunis ofaeotnnilid. The solu-- tion is filtered and evaporated to dryness in ocicuo at a temperature not exceeding 50.

C. The crystals are then powdered and dried thoroughly at 50 C. andniay be made in molded tabletsvby the use of a mixture of benzin and alcohol as a granulating fluid or any other non-aqueous fluid. The product. thus obtained is of a stable nature and (iopies of this yatent may be vdetained for five cents each, 'by addressing the Commissioner of Patents, V
